Obtaining IUE Data

The IUE Archive is currently maintained at the Space Telescope Science
Institute (STScI) as part of MAST, the
Multi-mission Archive at STScI.
The data are stored in gzipped compressed format online.
The IUE archive contains data processed
from both the IUESIPS and NEWSIPS data processing systems.
Primary access is via the web
although alternatively, users may
download IUE files via ftp.

Normally web users will search the IUE database for particular files
using the
IUE search page.
The returned table of found entries will
allow the user to mark the images to be downloaded. Alternatively,
if the
camera and image numbers are already known, they can be directly entered into
the IUE data
Retrieval page.
Your request for data begins a retrieval job.
The files are written to a data distribution disk area on the system, bundled
into a tar format file, and downloaded to the
disk area specified by the user in the "save as.." pop-up window. The files
are downloaded when the pop-up window disappears.

If you have problems reading the file formats, please check our
data retrieval help
page for suggested ways to read and interpret the downloaded
compressed files.
